The labour-intensive sector contributes about 14 per cent to the country's overall export. The drop in shipments is mainly due to negative growth in export of gold jewellery, gold medallions and coins and rough diamonds.

Gold jewellery shipments during the period declined about 8 per cent to USD 1.30 billion. Similarly, export of gold medallions and coins and rough diamonds contracted by 18 per cent and 5 per cent, respectively.

However, silver jewellery export went up to USD 2 billion in April-August 2017-18, from USD 1.67 billion a year ago.

Export of cut and polished diamonds reported a growth of just 0.51 per cent.

According to GJEPC, the sector is facing issues related to compliance of the Goods and Services tax (GST). It had demanded exemption from Integrated GST (IGST) on procurement of precious metals from nominated agencies for the purpose of manufacturing and export of jewellery.

According to the data, import of rough diamonds rose by 8.84 per cent to USD 7.7 billion in April-August.
